Craters-Unnamed_Crater_in_Terra_Cimmeria-MGS-PCF-LXTT.jpgUnnamed Impact Crater wth Gullies (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)201 visiteCaption NASA originale:"This MGS-MOC image shows a 1,5 mt (~5 feet) per pixel view of an Unnamed Crater in the Terra Cimmeria Region of Mars. Several Gullies extend from near the top of the Crater Rim, downslope toward the Floor of the Crater. Liquid water might have played a role in their genesis".

The orientation of the Dunes — with the steep faces toward the South — suggests that winds generally blew from North to South at the time the Dunes were formed".

Flow_Features-Zephyria_Planum-PIA03066.jpgFlow Features in Zephyria Planum (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 242 visiteOriginal caption:"This MGS-MOC image shows the broken, platy texture of Flow Surfaces in the Zephyria Region of Mars. Some investigators have suggested that these materials represent the remains of an ice-covered lake; others suggest that these are the Surfaces of hardened Lava that - when it was erupting - was very hot and fluid. Although not illustrated here, a key piece of evidence against the ice-covered lake hypothesis is that there are some small Craters formed on these Surfaces, and some of them have Boulders in their Ejecta Blanket. The Boulders indicate that the material is rock-solid".

Craters-Lau_Crater-M07_4748_4749-PCF-LXTT-01.jpgBizarre-looking "Dark Spot" near Lau Crater (EDM - Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)197 visiteLa chiazza scura e senza nome che la NASA stessa definisce di "natura sconosciuta" potrebbe essere l'evidenza, secondo alcuni Ricercatori Americani ed Europei, di una minuscola area di Marte con "vegetazione". Si, avete letto bene: vegetazione, di un qualche tipo. In un'altra immagine della stessa zona, la macchia scura appare di colore verdastro e non nero. E' del tutto evidente che i sostenitori dell'idea che si tratti di vegetazione (si, ma che tipo?) ritengono che l'immagine NASA sia manipolata, mentre la NASA sostiene che i colori che vedete sono "almost real" e quindi la macchia scura, comunque, non è (nè potrebbe comunque essere) vegetazione.
Questi sono i dati e le informazioni disponibili: come vedete, c'è materiale su cui riflettere...MareKromium

Craters-Lau_Crater-M07_4748_4749-PCF-LXTT-00.jpgFeatures and Proximities of Lau Crater (CTX Frame - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team) 177 visiteCaption NASA:"The Martian Southern Hemisphere was nearly 2 months into its Spring Season when this picture was taken by the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) on September 25, 1999. The scene covers a vast, Frost-coated Plain located South of the martian Antarctic Circle. The icy Terrain in the image has an almost pastel-like character, owing to the mixture of reddish Dust both on, in, and under the white Frost. The Frost - mostly frozen water at this time of year - is left over from Winter, which ended on August 2, 1999. One Martian Year is about 687 Earth days long, thus each of the Planet's 4 seasons are nearly twice as long as seasons on Earth.
The largest Crater visible in the upper left of the frame is Lau Crater, named for the Danish Astronomer, Hans E. Lau (1879-1918). The Dark Spot near the center of the image has no name, and its origin is unknown. The picture covers an area about 1.020 Km across by approximately 1.240 Km down.
The center is located near 76° South Lat. and 97° West Long.; North is toward the upper right. Sunlight illuminates the scene from the upper left".MareKromium
